To all'whom 'it may concern.'

Be it known that I, MARTIN pneu, a cltlzen of the United States, residing at Owatonno., in the county of Steele n nd Stat-e of Minnesota, have invented certain new and usefullImprovements in Combined Churns and Butter-lVol'kers, of which. the following is a specification.

This invention relates to improvements 1n the type of combined churns and butter Workers illustrated and described in Letters Patent of the United States No. 634,074, issued Oct. 3rd, 1899 to Dennis E. Virtue and myself and the objects of my present in` ventionare to provide improved means for reversin the butterworking rolls during the revo ution of the drum in the butterworlring operation; also to provide the drum with flights o rshelves for carrying the butter to the rolls, that are readily removable so that access may be had to the lower part of the drum when taking the butter out of the churn; and to provide improved means for .supporting the butter Working rolls within the drum and permitting their ready removal therefrom.

To these ends, my present invention cousists generally in the constructions and coxn 'inatlons hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a seci tional plan View of a combined churn and butter worker embodying my invention. Fig. 2 is a vertical longitudinal .section of a portion of the machine showing particularly the construction and arrangement of the operating mechanism. Fig. 3 is au end elevation of the machine looking in the drection of the arrow in Fig. 2. Fig. 4 is a transverse vert-ical section ot' the machine, said section being taken on the line of Fig. 1. Fig. is a vertical longitudinal section through a portion of the rear part of the machine.

In ull of the drawings 2. E! represent thc standards which constitute the principal part of the frame oi5 the machine. These standards are preferably connected by suitable angle hars 3, 3., and the framework formed by the standards and com'lccting bars is preferal'ily bolted to and supported upon suitable longitudinally extending timbers 4, 4. The churn drum or barrel is of usual form, preferably cylmlrical, and it is provided with door openings t, through 8, .so that said rolls may be which cream ma be placed in the drum, and through which tll'e butter is removed. These door openin s will in practice be closed cream-tight uring the c urning opera-tion, by means of suitable doors, (not shown). The drum is supported so as to revolve upon its axis, in the standards 2, 2, by means of suitable spiders 7 and 8 suitably secured to the drum-heads and provided with the trunnions 9 and 10. These trunnions are arranged iu line with cach other axially of the drum and form the means by which the drum and the rolls contained therein are supported in the standards.

I prefer to provide a single pair of butter working rolls 11, 11, which are arranged Within the drum in close proximity to each other and at opposite sides of the axis of the drum. These rolls are of any Ordinar or preferred construction, and they are preterably so mounted inthe drum as to be capable of ready removal therefrom. I prefer to support. these rolls by the followin means: Each roll is provided at' one en with a socket l2 having grooves 13. Stub shafts 14 extend through boxes 15 in the head ot' the drum and also have bearings in the spider 7` (see Fig. 2). These stub shafts are capable of rotating upon their axes, but are fixed against longitudinal movement by the collars 16 and pins 17. The shafts l-l are provided with lugs 18 that are adapted to titinto the grooves 13 in the sockets 1Q of the butter-working rolls, thereby couplin said rolls to said shafts and causing' sai( rolls and shafts to rotate together. At the opposite ends the rolls 11 are provided with the short trunnions 19 whici are seated in suitable boxes 20 projecting inwardly from plates 21. The plates .21 arc of circular form, preferably, and secured to their inner faces are the wooden disks 22 which t into circular holes in the end of the drum. The plates 21 and disks 22, which I have shown of circular form, but, which might be of any other suit a'blc form, close tightly the o ienings in the ends of the drum, and said dslts Q2 are apertured for the boxes 20u-'hielt receive and support the roll trunnions 1U. The openings into which the disks 22 fit, arel of suf- 'iclent size to permit the insertion or removal through them of the butter-working rolls` und those openings are located op 0- sitc the spaces between the legs of the spi er inserted or removed while the drum is supported by the spiders T and 8 upon the standards. For holding the platee`21 and disks 22 firmly in position, 1 provide the crossbar or crossheud, 23, formed with a bearing lug 24 that rests against the inner end of the drum trunnion. At. its ends this cross-head is provided with set-screws 25, 25, the ends of which engage the plates 2l. By screwing up these set-screws the plates 21 and disks 22 are firmly seated in the openings of the drum-head and a eream-tight closure of these openings is secured. When it is desired to remove the rolls, the set-screws are loosened, the cross-head taken out, and the disks 22 and the plates 21 to which they are attached, may be removed and the rolls may then be drawn, out through the open ings in the drum-head, the sockets atthe opposite end sliding out of connection with the stub-shafts to which they are coupled as hereinbet'ore described.

I rovide between cach of' the butterworkmg rolls and the wall of the drum, a longitudinal butter-carrying shelf, or, preferably, two such shelves 26 and 27. These shelves are preferably arranged. in substantially the relation shown in Ifig. d of the drawings to the butter-working rolls, so that, as the drum rotates, the butter which accumulates in the bottom of the drum, is carried upward and directed between the rotating rolls, and it paes again into the bottom of the drum to be taken up a ain by the next sucoeedin and so on as long as t e drum is rotated. I prefer to sup ort the inner shelf 2'." on the side of the um having the door openings, by apivotal connection with the rum-head, so that said shelf may be turned up in the position shown by dotted lines in Fig. 4 when it is desired to remove butter from the bottom of the drum. I prefer also to provide, below each pair of shelves and at a point near the center of the drum, a bracket 28 upon which the center of the pivoted shelf rests when in work ing position as shown in F ig. 4 and which also forms a support for the other shelf :26. This shelf 26 is preferably made in two sections, each having one end supported in a groove or casting on the inside of the drumhcad, and the other ends of the sections abutting together and resting upon the castinfr 28, to which they are secured by suitable bolt-s 29. rl`his construction enables me to readily remove any section of the shelves for renewal or repairs. I also prefer to provide auxiliary shelves 30, supported 1n the drum by brackets 31 and arranged preferably about nud-way on the inner cn'cunr ference between the other pairs of shelves. 'lhese auxiliary shelves carry up some of the butter which then slides oli' said shelves to a point where it is close to the butterpair of she ves, E

working rolls. It then passes between the rolls in the usual manner.

While the machine is being used for churning, the butter working rolls have no rotation upon their axes, but whirl with the drum, and the rolls and shelves together serve as flights or beaters to assist in agitating the cream and thus causing the separation of the butter. During the working operation the rolls are connected, with the churn driving mechanism, so that said rolls are rotated in o iposite directions, and this rotation causes the surfaces of the rolls that are toward the ascending side of the drum body, to move toward each other, and, this rotation of the rolls is reversed at each half revolution of the drum, and thereby the faces of the rolls that ure toward the upward moving side of the drum will always be caused to turn inward toward each other. This is the same motion that is given to the rolls in the machine shown and described in the patent issued to Dennis E. Virtue and myself above referred to. In my present machine I have however, provided improved `means for imparting the desired rotation to the butter-workinv rolls and reversing the movement thereot at each half revolution of the drum.

I will now proceed to describe the drum driving mechanism und the' means that l. employ for rotating the rolls and reversing the motion thereof: One head of the drum is provided with the usual ring gear 32, which is engaged b v a driving pinion 33 ou the drivin shaft The shaft 34 is mounted in sultable bearings upon the frame of the machine and the drivin pulley 35 is mounted so as to rotate free y upon said shaft. Two clutches 36 and 37 are provided, one upon either side of said driving ulley. Levers 38' and 39 are also provided or operating these clutches, The clutches may be of any suitable or preferred construction. I have here shown radially movin# blocks i0 and 41 engaged by spring controlled pins 2, the inner ends of said pins bearing upon the conical. surfaces of the clutch hubs. Then the right hand clutch 36 is moved toward the driving pulley, said pulley is clutched directly to the shaft 34, and the drum is driven directly from said shaft. When the clutch 3T is operated the driving pulley clutched lo thc sleeve 43 which is mounted so as to rotate upon the shaft 3l. This sleeve carries a pinion 44 which meshes with a geni' 4:.'1 mounted upon n short shaft 46. Upon the hub of the fear 45 is a pinion 4T. Splned upon the stuft 34 is a gear 48 which muy he moved into or out of mosh with the pinion 4T. When it is desired lo drive the drum at a fast speed for churning. the drive is from the pulley 35 direct lo the shaft :il and then to the drum geur 3'.' through the pinion 33. "hon il. is desired -tfo drive the. drinn ati-n -slowxspeed motion .is

isleeve communicated.from the "pulley 'tli'mimgh thesleevc 43, pinion 44 gear 45, pinion 4i' and gear 48 to the shaft '34, pinion 33 and drum gear 32.

Mounted centrally in the drum trui'nuon i) is a shaft 51 which has splined upon 1t the clutch sleeve 52. This sleeve must rotate with the shaft but is capable of being moved longitudinally on the shaft by the hand lever 53. Mounted upon the shaft 51 are, the bevel gears 50 and 54 each of which has upon its inner face a clutch surface adapted to be engaged by one of the faces of the clutchsleeve 52. A spur inion 49 is secured to or formed inte a y with the hub .y of the bevel gear 5t), an the pinion 49 is 1n mesh with the gear 45 hereinbefore described. Secured to the arms of the spider 'i' is a cam ring 55 and a shipper rod 56 is mounted in bearings in the frame of the machine and carries at its inner end a wheel or roll 57 that bears against the face of the cam rin 55. A s ring 58 upon the shi per rod tent s to hold die wheel in the end o the this means the shipper rod is moved forward and back during each revolution of the drum. The shi per rod is suitably connected by means ofpa sleeve 58 and fori; 59 with the clutch sleeve 52, whereby as the shipper rod reciprocates, the clutch sleeve upon the frame of the machine 1s also reciprocated on the shaft 51, and thereby first one of said bevel gears is conneeted or clutched to the shaft 51 and then the other. A bevel gear 60 mounted upon i a suitable stud 61 meshes with the two bevel gears 50 and 54. At its inner end, the shaft a 5l carries a inion 62 which engages with i the internal rm gear G3 mounted upon one i of the stub sha ts 14. A gear 64 is secured j to or formed integrally with the ring gear 63 and this gear meshes with a similar gear i 435 secured to the other stub shaft 14. The ring gear 63 and gear 64 are also secured to the stub shaft upon which they are mounted. f

lVhen it is desired to work the butter, motion is imparted through the gear 45 to the gear 49 and bevel gear 50. This in turn drives the bevel gear 54 through the bevel gear 60. 1f the clutch sleeve 5:2 is in engagement with the bevel gear 54, the shaft 5l is driven in one direction and if it is in engagement with the other gear, said shaft W ith the construction and arrangement of 5 the gcarin as described, when the drivin i pulley is c utclicd to the sleeve 43, the sha 5 51 is driven first in one direction and then in the other, the reversal ot' motion being obtained from the drum body through the reciprocating shi per rod and sliding clutch 52, and tiercby the butter working rolls are rotated in one direction during a g half revolution of the drum and in the other i f drum, means direction during the other half revolution,

'and this motion of the rolls ell'ects the work lng of the butter in the manner already described.

I prefer to provide a lever (in, pivoted and provided with a fork 6T adapted to engage the shipper rod 56, for the pln'pose ot' locking Said rod and preventing a reciprocation thereof when the butter-working rolls are not being rotated.

I do not confine m self to the details of the constructions herein shown and described as it is obvious that the same may be varied in many particulars without departing from my invention.
